This process of dephasing and reduction in the amount of transverse magnetization is called transverse relaxation. A characteristic time representing the decay of the signal by 1/ e, or 37%, is called the T2 relaxation time (1).2 * is shorter than T2 (Fig 1), and their relationship can be expressed by the following equation (3), where Î³ is the gyromagnetic ratio: 1/T2 * = 1/T2 + Î³ Î´B inhom, or 1/T2 * = 1/T2 + 1/T2â², where 1/T2â² = Î³ Î´B inhom, and Î´B inhom is the magnetic field inhomogeneity across a voxel.
An average central ac will use 3000 to 5000 watts of power every hour for around 9 hours a day during the hotter months. Click calculate to find the energy consumption of a central air conditioner using 3500 Watts for 3 hours a day @ $0.10 per kWh. Running 3 hours a day is the same as running 9 hours a day for 4 of the warmer months. Cost Per Hour:
if i talk in bookish term:1 kWh is the amount of energy used by a 1kW (1000 watt) electric heater for1 hour. therefore, 1 unit is not equal to how many watts, its equal to energy i.e. 1Kwhr=3.6 megajoules, as we know energy is power*time.
